New records of one marine and two soil ciliates (Ciliophora: Intramacronucleata) from Korea

초록

In this study, we present new records to Korea for three ciliate species [Apogonostomum pantanalense Foissner, 2016; Keronopsis polychaeta (Borror, 1966) Jankowski, 1979; Frontonia canadensis Roque and Puytorac, 1972] collected from marine (F. canadensis) and moss-covered soil (A. pantanalense and K. polychaeta) habitats. We examined the morphology of these three ciliates based on live observations and protargol impregnation. The main characters of the three ciliates are as follows: A. pantanalense: cell size approximately 130×45 μm, tail-like posterior end, and 6 or 7 ventral cirral pairs elongated to transverse cirri; K. polychaeta: size approximately 140×90 μm and approximately 18 frontal coronal cirri and 5 transverse cirri; F. canadensis: cell size approximately 100×50 μm and approximately 88 somatic kineties, 3 or 4 vestibular kineties,and 5 postoral kineties.
